What is Data Engineering ?

In the world of big data, every job works together in order to understand the data collected and make the best use of it for the business. The role of a data engineer is to prepare the infrastructure like algorithms that data scientists and data analysts to analyze in order to enable the business to make the best decisions based on their findings.

What Is a Data Engineer? — Develop the Skills You Need For Your Career In data engineering

When we think of engineering, we often think about heavy machinery. We think of careers that involve hardhats and jumpsuits, careers that deal with many cogs and gears. But engineering is broader than that. Live Science defines engineering as “the application of science and math to solve problems.” When thought of in those terms, it’s no wonder that the data industry requires data engineers.

In the world of big data, every job works together in order to understand the data collected and make the best use of it for the business. The role of a data engineer is to prepare the infrastructure like algorithms that data scientists and data analysts to analyze in order to enable the business to make the best decisions based on their findings. And with an average of 1.7MB of data created per person per second in 2020, there’s plenty of data for data engineers to work with.

But what exactly goes into a career as a data engineer? What are the skills and university degrees that you need to pursue a career in data engineering? Let’s break that down.

What Do Data Engineers Do?

Data can come from various places, and it often depends on the business. For instance, the small independent bookstore might have a website, a Facebook page, or an app that allows customers to make orders remotely or connect with the store. Every time the customer engages with these elements, they create data which can be collected, analyzed, and used to inform future business choices. Even simply signing up with a username and password can create a cookie, which are used to identify that particular customer. A major corporation undoubtedly has a major online presence, as well as apps from which users create data.

All that data works to tell business executives how their customers prefer to engage with their business and what kind of services they wish to receive from them. It’s almost like a comment card that’s created by customer engagement itself. To interpret this data and to make the most of it requires teams of data professionals.

Data engineers are just one part of the team of big data professionals who work to optimize the data created and collected, but they are an important part. From small independent bookstores to major international corporations, data engineers help business executives to connect with their customer base. The role of a data engineer, in particular, is to develop data algorithms and infrastructures that make the data easier to analyze.

Some of the job duties of data analysts include:

Types of Data Engineering Jobs

There are a number of aspects to data engineering, so it only makes sense that there are a number of different types of data engineering jobs. One data engineer might focus more on the coding and development side of things, while another data engineer might have a more analytical bent. Here are the different types of data engineering jobs you might find:

Data Architect or Builder

Builders are responsible for developing the data pipeline infrastructures that all other data professionals within the business will use. They will save data from various cloud, streaming, app, or social media sources and create the collection processes to gather that data.

Database Administrator

Database administrators are responsible for testing, designing, and maintaining database systems that are used to store data once it’s collected. They not only get the database systems up and running but test them and optimize them for more efficient and secure operation. It’s the database engineers who ensure that data collection and storage all runs smoothly.

Analytical Engineer

An analytical engineer utilizes programming languages like Java, Python, and R and databases like SQL and NoSQL in order to better understand the data and marry data processing systems. Where database administrators ensure that the database runs smoothly, analytical engineers search for ways to optimize the processes in place and the way of working with them.

Data Engineering vs. Data Science: Are Data Engineers a Type of Data Scientist?

Engineering is a science and engineers are a type of scientist, so it’s understandable that data engineers and data scientists can often be confused. In fact, data scientist is often misused as a blanket term that encompasses data engineers, data analysts, and many other careers. However, the role of a data scientist is actually quite different. Think of a data engineer as an architect, creating the systems within which a data scientist works.

Data Scientists

Data Engineers

Data engineers are the organizers, designing, testing, and maintaining the systems in which data scientists are able to ask the questions needed of the business.

What Systems Does a Data Engineer Use? Tools for Engineering Data Effectively

It’s safe to say a data engineer needs to know their way around multiple data and programming systems in order to do their job well. In some cases, data engineers are the ones creating those systems. In others, they might work within existing systems to collect data and create the data architecture and database systems they need. Regardless, there are a number of tools and processes with which a data engineer should be familiar for their job, including:

And, of course, an engineer should have a creative mind for programming themselves in order to be the “architect” of big data. For that, a data engineer must have the right skills.

Data Engineer Qualifications — What Do You Need?

As with any other career, in order to be a data engineer, there are certain skills that you first have to master. Aspiring data engineers should both have the education and the skills in order to be eligible for a career in their chosen field.

Education Requirements for a Data Engineer

For any engineering career, a knowledge of math and sciences is a must. If you want to get started in a Data Engineering career, you can choose to pursue a Master's degree, but this is not mandatory. Our Data Science bootcamp is another option you can choose if you want to become a Data Engineer. Combined with an experience in web development, this bootcamp will definitely allow you to succeed in this position.

Technical Skills For a Data Engineer

But what does all that education earn a student at the end of the day? It earns aspiring data engineers valuable skills that they’ll be required to have when they apply for a position. Some of these skills will be required, while others will make candidates much more appealing in a job interview. These data engineering skills include proficiency in:

Personality Traits You Need For a Career in Data Engineering

It takes more than just technical skills and education to be a great data engineer. You also need the right kind of personality. A data engineering career can be a demanding one, and it may not be for everyone. However, character traits can be developed in the same way that skills can. If data engineering is your dream career, here are a few personality skills that you’ll want to hone:

How Much Money Do Data Engineers Make?

The world of data is constantly growing and all kinds of businesses find themselves in need of the help of a data engineer. Companies like Amazon, Hewlett-Packard, and Facebook all hire data engineers to help optimize their business through the use of data. Because of the increasing demand, a career in data engineering can be quite a lucrative one, often paying well into the 6 figure range.

According to Payscale, in the United States: the average annual salary of a data engineer at Amazon is $110,361. Facebook pays data engineers over $133,000 per year on average. Even gaming companies like Procter & Gamble hire data engineers, with an average salary of $79,000.

Beyond just the financial security of work as a data engineer, there’s also plenty of room for growth within the career. In some cases, data engineers go on to become senior data engineers, mastering their chosen field and passion. Others, however, grow from data engineer to data scientist. A data engineer who loves the building and software element of things might decide to take the next step and become a lead software engineer, a career that can pay as much as $142k each year from companies like Capitol One Financial Corp.

A career as a data engineer is both lucrative and fulfilling, and it could be just the beginning of your career as an engineer or a data professional.
